Vaillant · ecoTEC plus Boilers
The boiler is currently performing a self-test of the water pressure sensor. During this diagnostic test, heating demands are temporarily blocked.
Click steps to track your progress.
No user action is required, as this is a normal self-test function of the boiler.
Wait for the test to complete; heating demands will resume automatically once the diagnostic is finished.
If this status persists for an unusually long period, contact customer service for further assistance.
